MF2 wiring .. Faulty Controller?
hi, ive got a Turbo Technics Turbo Kit on my Sierra, Which has a MF2 controller. the car spits and pops, when trying to accelrate / coming on boost.. Ive tested the pressure switch, The diagrams state, +5v (orange) .. Signal wire (blue) .. However, when ignition is on, im getting +4.7v from the signal wire, and 0V from the Orange wire.. Is this a faulty MF2 controller ?
the rest of the wiring is right (triple checked) ..
any ideas what it could be?
